EDGE-STRIPFOR BOARDS.

SPECIFICATION forming part of Letters Patent No. 650,440, dated May 29, 1900.

Application filed Decmter 21,1898. serial No, 699,908. (No model.)

To all whom it may concern: v

Be it known that I, ALEXANDER F. WARD, a citizen of the United States,residing at M em phis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Edge-Stripsfor Boards, of which the following is a specification, reference being had therein to the accoinpanyin g drawings.

My invention relates more specifically to the manufacture of boxes and packages formed by nailing boards together along the edges; and the invention consists in inserting a wedge-shaped strip of wood into the ends of the board, all as more fully hereinafter de= scribed, and shown in the annexed drawings, in which Figure 1 is a perspective View of a board provided with myiniproved edge-strip. Figs. 2 and 3 are sections of box-corners, illustrating the use of my invention. Fig. 4c is a section through the top of a tobacco-box, showing my invention applied to the head of the box. Fig. 5 is a cross-section through a board grooved to receive the strip, and Fig. 6 is a cross-section of the strip detached.

A represents a wooden board in which the grain runs, as usual, in the longitudinal direction of the board, and B a strip of wood inserted into a groove 0, formed in one end of the board. The strip B is wedge=shaped in cross-section, with the grain of the wood running in the longitudinal direction of the strip, and it maybe of the same kind of wood as the board or of a diflerent kind. The re= cess C is cut into the edge of the board which runs at right angles to the board and is of a size corresponding to the strip, and the strip is firmlyseoured therein by means of glue or other suitable cement.

In practice my invention applies principally to boards cut from veneer for the purpose of using such boards in the construction of all kinds of boxes and packages or portions thereof, and ordinarily when nails have to be driven through both ends of the boards (in which the grain is at right angles to the edges) both edges receive the wedge-shaped strips.

In constructing boxes from veneer boards provided with edge-strips of this character it will be seen that the securing-nails will pass at right angles through the grain of the wood in both boards, whether the boards are joined as in Fig. 2, where the nail passes through two strips, or as in Fig. 3, in which the nail passes only through a strip in one board. Likewise in securing the heads D of tobaccoboxes made of veneer boards of this character by using liners E, as shown in Fig. 4, the strips in the edges of the head D will afford a stronghold for the nails, and the ends cannot swell and strain the box.

It is well known that boards cut of veneer are very liable to warp, and being of necessity thin it is not possible to make good boxes from veneer boards, as the nails will not hold when driven through the edges at the ends of the board; but by my improvement a good box can be made entirely out of boards cut from veneer, thereby efiecting a great saving in cost, as the grooving of the boards and insertion of the wedge shaped strips is a comparatively simple and cheap operation.

While strips of wood have been inserted heretofore into the edges of boards, such strips have been made of rectangular or substantially-rectangular cross-section, and they cannot accomplish as good results for the following reasons: First, the rectangular strips require the groove in the board made wide at the inner ends, and consequently the board is weakened and warping or splitting is not prevented, while the wedge-shaped groove does not reduce the thickness of the board at the inner end, and therefore does not weaken it, and therefore prevents warping and splitting; second, the wedge-shaped strip can be glued more firmly into its groove than a rectangular strip from which the glue is mostly scrapedoff on the insertion of the strip; third, the wedge-shaped strip can be forced home to a good snug fit in its groove, and it takes less glue to secure it firmly; fourth, the wedge shaped groove can be out cleaner than the rectangular groove, and the filling in of the groove is more quickly accomplished with the Wedge -shaped strip; fifth, the rectangular strip is not, by far, as good to nail into, as it is too narrow on the edge to catch the nail, while the wedge-shaped strip has a wider landing, and the nail can be driven more accurately through the strip and holds better;

hat I claim as my invention is- As an article of manufacture, a board hav-- ing a wedge-shaped recess formed within and extending the entire width of its end;a coating of glue upon the walls of the recess, and a Wedge-shaped strip fitting within and entirely filling the recess, the inclined sides of the strip being adapted to abut against the recessed walls without disturbing the coating upon the latter, substantially as and for the IQ purpose set forth;

In testimony whereof I affix my signature in presence of two witnesses.

V ALEXANDER F. WARD.
